I can now see #meshcore devices up to 500+ km away. Quite fascinating! (and no, dear "yes, but"ters, this doesn't mean I can reliably communicate with meshcore nodes over that distance. I never claimed it does.)

@jwildeboer

Fascinating, but also a clear indicator of a fairly broken mesh design.

@fribbledom @jwildeboer the design is fine for the Rocky Mountains

@hanscees @jwildeboer

Is that a specific benchmark I'm not aware of? 😆

@jwildeboer Hmmm... And where is CZ network? 🤔

@jwildeboer Can you reliably communicate over these distances or simply see the repeater adverts when there are good conditions?

You could test this by using the trace tools and checking a few long distance paths; it's in the app at the top right when you click on tools.

@jwildeboer mescore is indeed quite fascinating. My biggest problem is that their android app sadly isn't open source 
@jwildeboer i will probably get back into meshcore as soon as i find a device that doesnt crap out after 3 days. Still upset about my tdeck :(

@jwildeboer Goddamn it, Jan, you're giving me so much fomo with these posts.

Alright, where does one start? What device should one buy so that they _actually_ use it? I thought of using meshcore as a tracker for my backpack but apparently I'd have to recharge it every couple of days. So maybe an actual messenger device is better? I can have it plugged in on the desk.

@filiph @jwildeboer you can take a look at my blog post I wrote 2 weeks ago. The goal was to share info I would have appreciated before starting with it: https://blog.eischmann.cz/2026/02/15/uvod-do-meshcore/
Úvod do MeshCore

Odolná síť, která nezávisí na Internetu a mobilních operátorech a dokáže přenášet zprávy přes celou republiku? Ano, je to možné. Tohle zvládne Meshcore, který už měsíc objevuji. A protože jsem musel v začátcích hodně věcí zjistit a vyzkoušet sám, rozhodl jsem se, že napíšu takový úvod do této sítě, kde se dozvíte, jak funguje a [...]

@jwildeboer 500 km is pretty amazing; i doubt I could get that here. How high up is the antenna?
